Abstract
The utility model relates to a filler used for the saprobe membrane process, in particular to an improvement for the lightweight fluidized filler. The utility model is characterized in that inorganic honeycombed grain fillers and an additional weight hollow body are arranged in the hollow body. The inorganic honeycombed grain fillers with big specific gravity can be changed into suspending fluidization type biological fillers and can suspend at different positions under water according to the need. Furthermore, the inorganic honeycombed grain fillers is easily hung with films. The inorganic honeycombed grain fillers has an aerobic function. The internal void is favorable for the growth of concurrent oxygen microbe to make the bacterial colony of microbe on the fillers richer and give full play to the aerobic function and the concurrent oxygen function. Because the grain fillers are arranged in the large hollow body, the fillers are't easily run off. The fillers with big specific gravity provided inwards can not easily cause the intense collision and are favorable for the growth of biological films.
Description
Technical field
Utility model relates to a kind of saprobia embrane method processing and uses filler, especially about the improvement to the lightweight fluidized packing material.
Background technology
Usually adopt fluidized packing material in the saprobia embrane method, as bio-carrier, as use in the fluidized-bed process at hydrogymnastic fluidized packing material, by the filling surface attached microbial organism in the sewage is degraded.As the biologic packing material of forming by hollow grid and built-in sponge carrier as described in the Chinese patent 96247275.1; With the 03274410.2 described spherosome that is connected to form by interior endless belt and outer endless belt by tens of bow-shaped leaves, centre of sphere place is provided with a bio-carrier fluidisation filler of forming according to different quality requirement counter weight device.Aforementioned in actual use fluidized packing material after suctioning moisture and attached biological film, can make filler significantly increase weight as the former according to still existing some deficiency, the suspension function reduction, and final subsidence does not have the fluidized packing material effect in water bottom; Secondly, the not wear-resisting wiping of built-in sponge carrier, under the water body vigorous agitation, the long-time collision mutually of filling block friction can cause the sponge block wearing and tearing, makes packing specific area sharply descend, influence biological treatment efficient.Latter's specific surface area is big inadequately, influences processing efficiency equally.Use plastics Pall ring and propylene ball fluidized packing material in the engineering, the former specific surface area is relatively little, and latter's wearability is poor.Ceramic porous particle, the big biofilm of a kind of specific surface area of can yet be regarded as is easy to filler, but its quality is big, can not use as fluidized packing material, and particle is tiny, takes place with the water outlet leakage easily.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of long-pending bigger than table, the organism fluidization filler that wearability is strong.
The utility model purpose realizes, main improvement is to adopt to place the good inorganic particulate filler of intensity in the hollow body of surface hollow-out, and the hollow body of regulating counterweight, thereby makes the intensity height, the inorganic particulate filler that wearability is strong can be suspended in the water body, becomes fluidized packing material.Specifically, utility model organism fluidization filler comprises hollow out hollow body and built-in filler, it is characterized in that said built-in filler is inorganic porous granular filler, also has the counterweight hollow body in the said hollow out hollow body.
The said hollow out hollow body of utility model, its effect one is to hold body as built-in granular filler, and tiny granular filler is held wherein, can not cause filler to run off with water outlet, surface hollow-out helps fully contacting of built-in filler and water; The 2nd, but floating condition created for the filler that does not have the suspension function, in addition, can also effectively slow down collision friction mutually between filler particles, this also is favourable to the protection granular filler.According to above-mentioned functions, hollow out hollow body volume shape can be various solids, but wherein a kind of better be to adopt hollow out ball, for example involutory hollow ball of plastics hollow out.
Said built-in inorganic porous granular filler can be regular or irregular bead, the short tube body of the porous ceramics of various typings, and ceramic wool etc. have the bio-carrier of higher-strength and wear resistance.
The hollow body of said adjusting counterweight, main effect is a proportion of regulating whole filler body, makes it can be suspended in body in the treating water, makes the filler body can be the suspension fluidized state in water body.Can be adjusted to the type filler that floats according to the treatment process needs, also can be the suspension type filler that is suspended in the sewage, and hollow body can be designed to big hollow body as required, also can adopt a plurality of little hollow bodies.Wherein a kind of better is to adopt the plastic hollow ball; for making full use of the hollow body surface-area; a kind of being more preferably on the hollow body surface is bonded with filler particles by binding agent; it is damaged both can to have protected hollow bodies to be difficult for by the filler particles scratch, has also effectively increased filler biological simultaneously and has utilized specific surface area.
Utility model is owing to adopt the hollow out hollow body as placing the granular filler carrier, and adopts hollow body to regulate whole filler proportion (buoyancy), can make biologic packing material be suspended in different positions in the water body by required.Secondly, this structure can make intensity good, and heavy inorganic porous granular filler becomes suspension fluidisation type biologic packing material.In addition, inorganic porous granular filler biofilm is easy, and aerobic effect is not only arranged, and the internal void oxygen animalcule growth that helps holding concurrently, thereby makes on the filler microbe colony abundanter, can give full play to aerobic, the oxygen function of holding concurrently.Besides, because granular filler is placed in the big hollow body, filler is difficult for running materials flow and loses.Built-in high-gravity filler is difficult for causing sharp impacts, helps biomembranous growth.
Below in conjunction with two embodiments, further specify the utility model structure, but filler described in the embodiment not the concrete qualification to utility model, the similar granular filler of some functions can substitute equally, reaches utility model goal of the invention and function.
